Chapter 18 Endocrine Flashcards
(32 cards)
Hormones may affect the cells that do not have receptors for them
Wrong
Hormone affects only specific target cells with receptors that bind and recognize that hormone
Right
Cells have receptors for only one type of hormone.
Wrong
Which structures has only and endocrine function
Thyroid gland, adrenal cortex, adrenal medulla
What stores the hormones secreted by the hypothalamus.
Posterior pituitary
It causes an increase in the basal metabolic rate
Thyroxine
With respects to regulation of blood Ca2+ which two hormones are antagonists
Calcitonin and parathyroid hormone.
Thyroid hormone is the antagonist of calcitonin
Wrong parathyroid hormone
Out of the four prolactin, estrogen, oxytocin and aldosterone what does not have an effect on the breasts
Aldosterone
What secrete glucagon which act on liver cells (target cells) and raise blood glucose level
Alpha cells
How is the secretion of glucagon inhibited
By high blood glucose levels
What secrete insulin which lowers blood glucose level and increases glucose uptake by cells
Beta cells
The secretion of insulin is inhibited by
Low blood glucose levels
What hormones do not program T-lymphocytes
Thymopoietin, thyroxine
What causes suppression of inflammation and depress immune responses
Glucocorticoid
What nervous system affects the secretion of hormones from the adrenal medulla
Sympathetic
Epinephrine and norepinephrine are part or what kind of response and how do they effect the body
Fight or flight, increase heart rate, increase blood pressure, dilated airways to the lungs and increased blood flow to the heart
Hormones and organs the contain endocrine cells. Heart
Atrial natriuretic peptide
Hormones and organs the contain endocrine cells. Kidneys
Renin
Hormone and organ that contain endocrine cells. Placenta
Human chorionic gonadotropin
Anterior pituitary
Growth hormone, prolactin
Hypothalamus
Antidiuretic hormone, oxytocin
Pineal gland
Melatonin
Adrenal cortex
Aldosterone
